The present invention relates to a liquid desulfurization agent for removing sulfur compounds contained in exhaust gas, anaerobic digester gas, and biogas of a chemical process. The composition of the present invention comprises an iron complex formed from poly ferric sulfate [Fe_2(SO_4)_3] and N,N-bis (carboxyl methyl)-L-glutamic acid-4sodium salt [GLDA-4Na] and an iron complex formed from poly ferric sulfate [Fe_2(SO_4)_3] and ethylenediamine-tetra acetic acid-4sodium salt [EDTA-4Na] as an active ingredient. According to the present invention, the liquid desulfurization agent containing the iron complex as an active ingredient is easy to be handled and used and, especially the iron complex in accordance with the present invention has an excellent desulfurization effect and enables to use less amount of the desulfurization agent due to a high content of iron (Fe) with a catalytic activity. Therefore, the installation area for a desulfurization facility is greatly reduced, thereby installing ...
